How to make a demo on gzdoom

[undeadgamer9609]

I am having a freezing issue where gameplay randomly freezes for half a second before resuming when i start up GZDOOM i have changed the renderer, and resolution and that did not work and it is with ANY game and mod. i am using GZDOOM 4.14.0. My CPU is a AMD Ryzen 7 7800X3D 8-Core Processor 4.20 GHz, my ram is 32GB, and my GPU is a RTX 4090. And when i look on task manager during gameplay when the issue happens none are bottlenecking so it is not my system as far as i can tell. I have tried playing the steam version and noticed the same issue of freezing randomly for half a second when starting and i have verified the files that did not work.What could cause this.

Whenever i play doom, doom2, heretic, or any mods it freezes randomly for half a second during gameplay not like a stutter everything stops completely and music continues playing normally before gameplay resumes.

I am using GZDOOM 4.14.0 i have been using VULKIN and changed it to OPENGL, changed the resolution, and deleted the shader cache as well.

My specs are OS: Windows 11 home, CPU: AMD Ryzen 7 7800X3D 8-Core Processor 4.20 GHz, RAM: 32BG, GPU: RTX 4090.

I checked task manager after it happens and there is no bottlenecking at all they are not even close to maxing out the highest is around 50%.

There is no need to keep making topics on the same issue.

Most likely you're experiencing thermal throttle. Make sure you clean out the dust and vents in your computer and make sure that the computer is elevated off of the ground, not sitting atop any fabric or carpet, and just to be sure run a temp monitor.

If that's not the case then make sure you're not running too much in the background. Things like game launchers, web browsers, Discord, Skype, Slack, Overwolf, Curseforge, <insert whatever else here> can randomly consume too many CPU cycles and cause hiccups in performance.

And if yet even that isn't a problem it could be your PSU. You're probably pulling more wattage it can handle and it brown-outs the system. (Especially suspect since you said you're using an RTX 4090 - those things can't manage power properly at all)

Also make sure you're not running any files out of a OneDrive or Dropbox or Google Drive or any other sync'd folder. Files that run locally always run much faster.

Also some mods are notoriously known to be problematic with resource management, especially those in the category of Project Brutality or similar mods that spam actors all over the screen but do not make proper use of the various mitigations available that can help reduce processing time and make things run smoother - plus there's also other projects (mapsets) such as Eviternity that spam linedefs very heavily and run very poorly even on high end systems because the BSP walk for all the map geometry cannot complete in a timely fashion on every frame.

If none of that is an issue then I don't know.

I have a liquid CPU cooler and about 5 big fans in my case so thermal throttle should not be and issue.

I am not running much in the background because when i look at the task manager it only goes up to 50% rarely when playing so that can't be it.

I have a 1500 watt PSU so i have plenty of power.

I prefer the drag and drop method when using mods.

And it is not just mods it is the actual games that are also having problems.

I have also played it on the kex engine on steam and it happens there too but i have also played it on chocolate doom and i did not see the problem there.

The RTX 4090 is really suspect, especially when paired with an unknown PSU. These cards are absolutely notorious for their power consumption needs, and PSU manufacturers are also notorious for selling PSU's that are spec'd far higher than they actually perform, these two issues together create massive problems.

What PSU do you have? What is the exact make/model?

One thing you can try is undervolting the card. You might not get big gains from it, but you won't know if you don't try.

A CORSAIR HXI Series HX150I 80 PLUS platinum fuilly modular ultra-low noise ATX power supply is what is what it says on the website.

The weird thing is that i only have this problem with ID tech 1 games no other.

[Rachael]

The last culprits are the CPU and the OS then. If you say it happens in the Kex version it could very well be the CPU. Both GZDoom and the Kex version are CPU-heavy so stutters in the CPU's performance can cause these issues. Outside of that Windows 11 also likes to randomly draw power from the CPU for whatever-the-fuck-it-wants-to-do-without-your-permission-in-the-background also.

[undeadgamer9609]

That just it my CPU is not bottlenecking at all it barely hits 50% at times because i have a AMD Ryzen 7 7800X3D with 8 cores and 16 threads with V-cache and can go up 5GHZ.

The weird thing is i can play id tech 2 games like quake just fine but when i try to play id tech 1 games i have problems.

[Rachael]

You are being deceived by how the task manager presents CPU usage.

The BSP walk in both GZDoom and Kex is a single-core affair, and if your CPU is hitting 50% it's likely that multiple cores are at their max usage. With an 8-core CPU a single core fully utilized will only show 12.5% - likewise only 12.5% usage of all cores will still show as 12.5% - so just seeing "50%" is not telling the whole story.

[undeadgamer9609]

But i wonder what is causing only id tech 1 games to have issues and everything else works fine with no issues.

[dpJudas]

Kex and GZDoom are completely different engines so the fact that it is happening to both indicates it isn't the game/engine that is doing it.

It is more likely it is related to either a specific hardware component and/or subsystem in Windows. I have an ASUS monitor that freezes the mouse for a second just slightly after I turn it on. Some kind of fuckery going on in some driver. It could be the disk having issues if its the same file on disk being used for the test. It could be the processor overheating and throttling itself. Maybe the GPU is doing it. Way too many possibilities to list really. Just because your computer got the specs and setup that should make it work doesn't mean something couldn't be failing.

If this was my computer, I'd start out by upgrading all drivers in the system. Grab the latest CPU drivers. The latest GPU drivers. The latest motherboard drivers. Try update the BIOS for the motherboard. Then I'd clean the fans like Rachael suggested. I would try run various diagnostics tools to see if any of them show anything. I'd try unplug devices from the computer to see if it changes anything. Run some tool that can see the SMART data from the hard drive to see if it reports anything. I'd try run Open Hardware Monitor to see if CPU and GPU temps look normal or not. Those kinds of things.

[undeadgamer9609]

The thing is i can play doom eternal at 4k all setting maxed out at a solid 60 to even over a 100 fps no problem.

So i don't think my hardware is throttling or overheating because i have a CPU water cooler connected to my Ryzen 7800X3D.

And i check for updates every month to stay up to date.

[undeadgamer9609]

Could it be the wads that is the problem?

[Redneckerz]

Could it be the wads that is the problem?

Unoptimized wads can be a real problem, yes.

[undeadgamer9609]

But every single wad that i play?
